A light source control apparatus that includes a light quantity detection unit that respectively detects light quantities of three colors of light emitted from a light source part. The first semiconductor wafer is connected via the first intermediate layer to a second semiconductor wafer in such a way that a hermetically sealed cavity is defined by the recess. The auxiliary tubes each contain a plurality of apertures for the rapid and efficient movement of dialysis solution in and out of the peritoneal cavity. A magnetic ring receives and retains the birefringent crystal wedges and the optical rotator together. The helical channel can form a vortex flow of the metal particulate, and the mixing conduit can form a vortex flow of the air metal mixture.
